From the ecological prospective, the singularity-induced bifurcation will lead to a surge in a population density within a short period of time and eventually break the ecological balance.
Rivers play an important role in people׳s living and agricultural production, however, intense human activities have broken the original ecological balance, and affected structures and functions of the river ecosystem.
They highlight, after examining 28 such variables, that foreclosures, problem landlords and broken street lights represent "ecological advantages" for the development of open-air illegal drug markets.
All of these results suggest that inoculation with biocontrol agents breaks the original ecological balance of soil microbial community; however, a progressive recovery is commonly observed following fading of the released strain.
Countries and islands of type localities are usually broken down to states, provinces, archipelagos, ecological zones, towns, and villages.
It is assumed that the chain of the above listed events from cultivation to ecological harm is obviously broken at one or more links [7].
When such ecological barriers break down for animals--for example, when two species of Darwin's finches colonize the same Galápagos island--hybridization can occur, blurring the lines between species.
Similar changes might occur for species pairs with allotopic distribution patterns, e.g. if ecological barriers break down due to habitat deterioration or alteration [ 24, 29, 30].
Because of the ecological effects of human activities and industry, more and more habitats are broken into patches and some of them are polluted.
The ecological effects caused by fishing gear that is lost when cut or broken after snagging on the bottom is a growing concern to managers and scientists.
